摘要：The application of wireless sensor network consists of a wide variety of circumstances such asenvironmental observation, intrusion detection, and battlefield surveillance. The network is composed of a significantnumber of nodes distributed in a different area in which not all nodes are directly connected. These nodes are equippedwith limited with battery power and capable of wireless communication. Resource limitation has to be taken care whiledesigning wireless sensor network infrastructure. In wireless sensor network how to conserve the limited power sourceto extend the network lifetime.In this paper we proposed a EASR(energy aware sink relocation) to extend the networklife time which deals with the residual battery energy of each sensor nodes to adjust the transmission range and relocatethe sink.
